Prism Sound ADA-8XR Multi-channel A/D D/A Converter Operation Manual - Revision 1.00 2 Getting Started This section is intended to get you going quickly, without the need to read the entire Operation Manual. This is quite feasible if your application is fairly ‘standard’; if not, you may need to refer to other parts of the manual to get exactly what you need. If your ADA-8XR is to be used with a direct workstation interface, such as Pro Tools, please refer to the appropriate ‘Getting Started’ section in the Module Reference (volume 3). 2.1 Connecting the ADA-8XR First, check that the line voltage setting matches your local voltage; if not change it by reorienting the voltage selector in the power inlet on the rear of the unit. Two ranges are selectable: 180-250VAC or 90-125VAC. Details of how to switch between ranges are in section 6.1. Connections to the analogue inputs and outputs are via panel-mounted XLR connectors. Connections to digital inputs and outputs may require the use of a breakout cable (supplied) according to the formats fitted to your unit. Direct connection to a workstation may require the use of the workstation manufacturer’s cable. Refer to the appropriate section in the Module Reference for connection details and example diagrams. Analogue Monitor outputs are on RCA (phono) sockets; stereo digital Monitor out is on BNC (RCA/phono adapter included); AES11 ref sync I/O are on XLRs; wordclock ref sync I/O are on BNCs; serial comms (jumpered for RS-232) is on DB9 male. Plug in the unit and switch on the power switch which is integral to the power inlet. The ADA-8XR should briefly light all LEDs, then settle into its default setup with the level screen displayed on the LCD display. The unit can thereafter be turned off and on using the ‘Standby’ key in the top left-hand corner of the front panel. 2.2 Configuring the ADA-8XR The user-interface of the ADA-8XR is a ‘three-tier’ system. If your application is fairly standard, you will probably be able to load a ‘Factory Store’, and be up and running straight away. There may be a few changes which you need to make to the loaded Store, which you can most easily do using the blue ‘Access’ buttons to take you straight to the Menus you need. If your application is unusual in its details, you may need to navigate the Menu system manually. First, have a look at the available ‘standard’ Factory Stores at the end of the Firmware Reference. These apply to most non-workstation applications. If you’re using a dedicated Workstation I/O Module, look instead at the Factory Stores section for that Module in the I/O Module Reference. Hopefully one of the Factory Stores will be either exactly what you need, or close to it. Select the most appropriate Factory Store by pressing the ‘Bank’ button at the bottom left of the Menu Panel until the desired Bank of Stores is shown in the LCD display. Then press the desired Store number button. At this point, the name and number of the desired Store should be displayed, along with the message: “Load”. Press the ‘Enter/Accept’ key to load the Store. If the Store you loaded requires further modification, the easiest way to do this is to use the blue Access buttons which are distributed over the ADA-8XR’s Front Panel. The Access buttons on the Mimic Panel (block diagram) area are the most likely to be useful. Using the ‘Path’ select button in the top left-hand corner of the Mimic Panel, choose the Path who’s © Prism Media Products Limited, 2001-2004 Page 1.8
Prism Sound ADA-8XR Multi-channel A/D D/A Converter Operation Manual - Revision 1.00 settings you want to modify. Normally Path 1 is configured as the A/D Path and Path 2 as the D/A Path, although other variations are possible – check that you are dealing with the desired Path by observing the signal flow indicated by the LEDs on the Mimic Panel in each of the states of the ‘Path’ selector button. Choose the appropriate Access button to take you to the first parameter you want to alter. For example, if you want to change something to do with the analogue input of an A/D Path, press the Access button in the ‘Source’ box. This action takes the Menu Panel (with the LCD display) directly to the cluster of Menus which deal with the analogue inputs. Pressing the SOURCE Access button again moves to the next analogue-input-related Menu and so on, in a cyclic fashion. When you have found the Menu you want, you should be able to alter the desired parameter using the Menu keys (in combination with the Channel Select buttons at the bottom of the Meter Panel if the parameter must be altered per-channel). If you can’t find how to access the desired parameters, refer to the Firmware Reference. If the parameters are obscure, you may need to navigate the Menu system manually without the help of the Access buttons. Finally, you should be able to check the correct operation of the ADA-8XR in system by using the eight bargraph meters on the Meter Panel, and perhaps also the two-channel Monitor feature, which is controlled from the Monitor Panel at the left-hand side of the unit. Note that both of these Panels are also assignable to either of the two eight-channel Paths with their own [Path] selector buttons. © Prism Media Products Limited, 2001-2004 Page 1.9
